7 Claims.

This invention relates to improvements. in rug weaving frames.

A primary object of the invention is to provide a simple and sturdy rug frame adapted to be manufactured at a low cost.

A further object is to provide a device of this type wherein stresses imparted to the frame proper, due to contraction of the woven material during construction, are not transmitted to any of the supporting members.

A'still further object is to provide improved joints enabling the frame to be knocked down during periods of no-nuse. The parts comprise a mailable package.

Other objects and advantages will become apparent to those skilled in the art upon examination of the drawing, specification and the claims appended thereto.

In the drawing:

Figure l is a view in perspective of the improved rug weaving frame.

Figure 2 is a view of a frame stringer member which is used only when rugs of a size smaller than the entire frame dimensions are woven.

Figure 3 is an enlarged fragmentary view in perspective showing the method of frame assembly.

Figure 4 is a section taken along line 4-4 of Figure 1.

Figure 5 is a section taken along line 5-5 of Figure 1.

Like parts are identified by the same reference characters throughoutthe several views.

The device, as best shown in Figure 1, comprises a generally rectangular rug weaving frame and a base structure which provides adjustable support for said frame.

The support includes a pair of base members I1 and I8 which provide support for vertical members I9 and 20, respectively. Rigidity of the vertical members is preferably obtained through the provision of a pair of cross arms 23 and 24, the base members I! and I 8 being preferably connected by at least one stringer bar 26.

The lower termini of base members I9 and 20 are preferably mortised to provide rigid joints with base members Hand I8, said joints being maintained under pressure provided by a pair of bolts 28 and 29 which allow the vertical members and their adjoining cross bars to be removed as a unit for shipment or storage.

The weaving frame includes side members I0 and II and end members I2 and I3 supplemented by a pair of elements 30 and 3|, which are tiltably mounted by means of bolts 33 to the upper endportions of the vertical posts 20. The heads of bolts 33 are preferably countersunk within the supporting elements 30 and 3|, as shown in Figure 4, and are provided with wing nuts 35 to facilitate removal and assembly thereof. End members I2 and I3 are fastened to the support elements 30 and 3f by nails or glue, or otherwise. The side and end frame members have their termini mortised, as best shown in Figure 3, to provide rigid joints as shown in Figures 1, 3 and 5, said members being, maintained in joined relation by means of clamping bolt 38 which carries a downwardly dished washer 39 at its head portion and is provided with a washer 48 and a wing nut 41 at its lower portion.

Through the provision of the large size dished washer 39 clamping stresses are distributed equally over a substantial portion of the mortised end of each frame. end member, thereby greatly reducing the possibility of these end portions splitting under the clamping pressure.

Both the side and end members of the frame carry a plurality of equally spaced pegs 45, about which the yarn or other rug making material is looped during the weaving process. It is important that these pegs are sufficiently strong to withstand a substantial side pull. I have found that during. rug weaving the yarn is apt to absorb moisture, causing a contraction thereof, with the result that the pegs are broken if they do not possess sufficient strength to withstand the pull. Pegs 45 preferably comprise an upper cylindrical portion 46 and a lower reduced cylindrical portion 41, as best shown in Figure 4. Reduced portion 41 is disposed within a complementary bore provided in the frame member, where it is secured by an adhesive such as glue. A side pull on such a peg is partially absorbed by the annular shoulder provided between the two portions in the top surface of the frame member. Hence it is very hard to break, and it is not apt to become dislodged due to the bore becoming enlarged.

To prevent the elongated side members Ill and II from distorting due to the stress above men tioned the transverse brace I4 is provided, as heretofore mentioned. Brace I4 is removable, and it may be replaced by the peg carrying member 50 shown in Figure 2 adjustable to various positions along side members Ill. Member 50 includes a lower portion 5| and a shortened upper member 52, which is preferably nailed thereto, and which carries a plurality of plugs identical with those heretofore described in connection with the side and end frame members. When member 50 is substituted for brace M a smaller rug may be woven in the square at either end.

I claim:

1. In a device of the character described, the combination with spaced supporting posts, of a frame structure pivoted therebetween and comprising side members and end members, each of the end members comprising upper and lower plies and each such end member having one of said plies reduced in thickness sufiiciently to receive the end of a side member and to provide a shoulder abutted by the side member, said side members being positioned between the reduced thickness portion of the last mentioned ply and the other ply against said shoulder, and means passing through the plies of the end members at the corners of the frame structure and between the end portions of the side members positioned between said plies, whereby to clamp said frame structure together, and means for pivotally mounting said end members to said osts. p 2. In a device of the character described, the combination with spaced supporting posts, of a frame structure pivoted therebetween and comprising side members and end members, each of the end members comprising upper and lower plies and each such end member having one of' said plies reduced in thickness sufficiently to receive the end of a side member and to provide a shoulder abutted by the side member, said side members being positioned between the reduced thickness portion of the last mentioned ply and the other ply against said shoulder, and means passing through the plies of the end members at the corners of the frame structure and between the end portions of the side members positioned between said plies, whereby to clamp said frame structure together, and means for pivotally mounting said end members to said posts, said lower plies being continuously of one thickness throughout their extent and the upper plies of the end members being the plies relieved to receive the end portions of the side members as aforesaid, said side and end members being provided at predetermined intervals with projecting pins, for the support of rug weaving material.

3. A device of the character described, comprising in combination as a rectangular frame, side members, end members comprising upper and lower plies in face contact between said side members, at least one ply of each such end member being of reduced thickness to accommodate the end portion of the intervening side member, while providing a shoulder laterally abutted by the end portions of the side member, each end of each side member being received between portions of the upper and lower plies of the respective end .members, a bolt passing through the interengaged end portions of the respective side and end members at each corner of the frame and provided with a head, a cupped disk apertured to receive the bolt and confined beneath the head and constituting means for distributing the pressure of the bolt, and a manually operable nut threaded to the bolt and constituting a means for tightening the bolt to effect a clamping engagement between the interleaved end portions of the side and end members comprising said frame.

4.
